Gavin Strang: I thank the Secretary of State for his statement and his response to the Select Committee report. Does he accept that bovine TB is the biggest challenge facing our livestock sector? Over the past five years up to last March, it has cost the Government well over £4 million pounds, and in addition there is the huge commercial cost and the misery and suffering resulting from herd breakdown. Will the Secretary of State say a little more about not only cattle-to-cattle spread, but herd-to-herd spread?
